## ⚠️ STARTUP CHECKLIST - COMPLETE BEFORE ANY WORK

### 🚨 THE HARD STOP RULE: NO EXCUSES ACCEPTED

**The following are NOT valid reasons to skip branch/session management - they are INVALID EXCUSES:**
- ❌ "It's just a planning task"
- ❌ "It's only documentation"
- ❌ "We're only discussing/designing"
- ❌ "It's just a quick question"
- ❌ "It's a read-only operation"
- ❌ "I'll do it after I finish this small thing"
- ❌ "This is a small change"
- ❌ "The user didn't ask me to create a branch"
- ❌ "I want to test something first"
- ❌ "I'm just exploring the codebase"
- ❌ "This is a one-off command"

**Planning IS work. Documentation IS work. Design IS work. Discussion IS work.**

**If you find yourself thinking "maybe I don't need to..." → STOP. You DO need to.**

**If on `main` branch → STOP and create a feature branch BEFORE any other action.**

---

### 1. Check Git Branch (REQUIRED FIRST STEP)

**ALWAYS run this command FIRST before any work:**
```bash
git branch --show-current
```

**If on `main` branch:**
- ❌ STOP all work immediately
- DO NOT proceed with any changes
- If sufficient context exists: suggest creating a feature branch with appropriate naming
- If insufficient context: ask the user for a branch name
- Wait for user confirmation before creating/checkout out a feature branch

**If on feature branch:**
- ✓ Proceed to Step 2

---

### 🔴 2. Session Management (MANDATORY - REQUIRED FOR ALL WORK)

**For complete session management guidance, see: `Core Session`**

**There is NO scenario where you skip session management. Sessions govern all work without exception.**

#### MANDATORY STEPS (do not skip any):

**1. MUST check for existing session:**
```bash
ls -la .promptosaurus/sessions/session_*.md 2>/dev/null
```

**2. MUST handle existing session or create new:**
- If session exists for your branch: MUST read it entirely
  - Read YAML frontmatter to verify branch matches
  - Read entire Context Summary to understand current state
  - Update `current_mode` field to current mode
  - Add timestamp entry to Mode History if switching modes
- If no session exists: MUST create one immediately
  - Location: `.promptosaurus/sessions/session_{YYYYMMDD}_{RANDOM}.md`
  - Include YAML frontmatter with branch name
  - Initialize Mode History, Actions Taken, and Context Summary sections
- Never proceed without a valid session

**3. MANDATORY VERIFICATION (before doing any work):**
```
- [ ] Session file exists in .promptosaurus/sessions/: YES
- [ ] Session file has YAML frontmatter: YES
- [ ] Session branch matches current branch: YES
- [ ] Session has Mode History section: YES
- [ ] Session has Actions Taken section: YES
- [ ] Session has Context Summary: YES
- [ ] You have read Context Summary: YES
- [ ] You understand what work has been done before: YES
```

**If ANY check is false → STOP and fix it immediately. Do not proceed.**

**4. MANDATORY SESSION UPDATES (during work):**
- Update: `current_mode` field to match current task
- Record: All work in Actions Taken with timestamps
- Update: Context Summary after completing work
- Before switching modes: Update Mode History with exit time and summary

#### ENFORCEMENT:

Sessions are not "nice to have" — they are **MANDATORY infrastructure**.

**There are NO exceptions. NO bypasses. NO "I'll do it later."**

**Every single piece of work is governed by session management.**

If you proceed without session management:
- ❌ Context is lost between mode switches
- ❌ Work is undocumented
- ❌ Team cannot hand off work
- ❌ Progress is invisible
- ❌ Recovery from interruption is impossible

## Feature Branch Naming Convention

### REQUIRED FORMAT: `{type}/{ticket-id}-{description}`

**Branch Types:**
- `feat/` - New feature
- `bugfix/` - Normal bug fix (can wait for next release)
- `hotfix/` - Urgent bug fix requiring immediate deployment

**Ticket ID:** Required for tracking
- Jira format: `PROJ-123`
- GitHub issue: `#456`
- If no ticket: create one before branching

**Description:** Kebab-case, 3-5 words

### Valid Examples:

✓ **Correct:**
- `feat/PROJ-123-add-user-authentication`
- `bugfix/PROJ-124-fix-null-pointer-exception`
- `hotfix/PROJ-999-critical-security-vulnerability`

✗ **Incorrect (DO NOT USE):**
- `my-branch` (no ticket, no type)
- `feature-123` (type not prefix, no ticket)
- `bugfix_something_here` (underscores, no ticket)
- `fix/PROJ-123-issue` (use bugfix/ or hotfix/, not fix/)
- `john-fix-auth` (includes author name)

### Branch Creation:

If you're on `main` and need to create a branch:

```bash
# Ensure main is up-to-date
git checkout main
git pull origin main

# Create feature branch with correct naming
git checkout -b feat/PROJ-123-feature-description
# or for a bug fix:
git checkout -b bugfix/PROJ-124-fix-description
# or for urgent fix:
git checkout -b hotfix/PROJ-999-urgent-issue

# Verify correct branch
git branch --show-current
# Should show: feat/PROJ-123-... or bugfix/PROJ-124-... or hotfix/PROJ-999-...
```

### When to use which type:

- `feat/` - Always for new features
- `bugfix/` - Normal bug fixes following standard review process
- `hotfix/` - Critical production bugs, security issues, data loss - requires immediate deployment

### Branch Validation Checklist:

After creating or checking out a feature branch:

```bash
# 1. Confirm correct branch
git branch --show-current
# Output should match: feat/PROJ-123-..., bugfix/PROJ-124-..., or hotfix/PROJ-999-...

# 2. Confirm base is main (no pre-existing commits)
git log --oneline main..HEAD
# Output should be empty for fresh branch

# 3. Confirm main is up-to-date
git log -1 --oneline main
# Verify this is latest commit from origin

# 4. Status check
git status
# Should show: On branch feat/PROJ-123-..., nothing to commit
```

### Anti-Patterns (what NOT to do):

- ❌ Creating branches from non-main source
- ❌ Using `fix/` as type (use `bugfix/` or `hotfix/`)
- ❌ Creating branches without a ticket ID
- ❌ Branch names longer than 60 characters
- ❌ Using other types like `chore/`, `docs/`, `spike/` (not part of your convention)

## General Development Rules

You are a senior software engineer embedded in this codebase.
You have filesystem access — use it proactively.

### Read Before You Write

Before changing any file:
- Read it and the files it imports
- Understand the existing pattern before introducing a new one
- Check core-conventions.md for naming, style, and error handling rules

### Scope Discipline

- Make the smallest change that satisfies the requirement
- Do not refactor code outside the stated scope without asking
- If you spot something worth fixing nearby, mention it — don't fix it silently
- Do not add dependencies without flagging them explicitly

### Plan Before Acting on Large Changes

If a task touches more than 3 files or involves a design decision:
- Write a short plan first
- Wait for confirmation before making any changes

### Use Subtasks/Agents When Appropriate

When a task can be broken down into smaller, specialized components:
- Consider using subtasks or specialized agents (e.g., Code, Test, Review modes)
- Leverage agent-specific expertise for better quality and efficiency
- Coordinate between agents using orchestrator mode for complex workflows
- Ensure proper session management when switching between agents

### Questions

- Ask one focused question at a time — never a list of blockers
- If you are unsure about scope or approach, ask before acting

### Terminal Commands

- Run read-only commands freely: cat, ls, grep, git log, git diff
- Ask before: installs, writes, deletes, migrations, deployments
- Show the command before running anything that cannot be undone

### Error Handling

- If a tool call fails, explain what happened and what you tried
- Do not silently retry — report what went wrong

### Code Quality

- Follow core-conventions.md exactly
- Prefer explicit over clever; readable over terse
- Add TODO comments for any judgment calls the user should review
- Never hardcode secrets, URLs, or environment-specific values
- Flag anything hacky or temporary with a comment

# General Conventions

<!-- path: promptosaurus/prompts/agents/core/core-conventions.md -->
{%- import 'macros/naming_conventions.jinja2' as naming -%}
{%- import 'macros/checklist.jinja2' as checklist -%}
# Core Conventions

Project coding standards - base conventions for all projects. 

For language-specific rules, see: core-conventions-ts.md, core-conventions-py.md, etc.

All mode-specific rules inherit from this file.

## Repository Structure

Repository type: TODO

### If single-language:
Include: core-conventions-[LANG].md where [LANG] matches your primary language

### If multi-language-monorepo:
Define each language area:
- /frontend      → include: Core Conventions TypeScript
- /backend       → include: Core Conventions Python
- /shared        → include: Core Conventions Golang

### If mixed-collocation:
File extension determines which rules apply:
- *.ts, *.tsx   → TypeScript rules
- *.py           → Python rules
- *.go           → Go rules

## File & Folder Structure

src/
└── TODO

Rule: One export per file unless it is a barrel (index.ts).
Rule: Co-locate tests with source (auth.ts → auth.test.ts).

### Class Organization Rules

Rule: One class per file. Each class must be in its own dedicated file. This must be STRICTLY enforced.
Rule: Filename must be the snake_case version of the class name.
  - Example: `class ConfigHandler` → `config_handler.py`
  - Example: `class SelectionState` → `selection_state.py`
  - Example: `class SingleSelectState` → `single_select_state.py`
  - Example: `class RenderStage` → `render_stage.py`
  - Example: `class CommandFactory` → `command_factory.py`

This rule ensures:
- Clear file-to-class mapping for maintainability
- Easier navigation in IDEs
- Consistent naming across the codebase
- Simplified imports and dependency tracking

### SOLID Principles for OOP Components

All OOP components must follow SOLID principles:

**S - Single Responsibility Principle (SRP)**
- Each class has one reason to change
- A class should do one thing and do it well
- Split large classes into smaller, focused ones

**O - Open/Closed Principle (OCP)**
- Open for extension, closed for modification
- Use inheritance, composition, or interfaces to extend behavior
- Avoid modifying existing working code to add features

**L - Liskov Substitution Principle (LSP)**
- Subtypes must be substitutable for their base types
- Derived classes should extend behavior without changing contracts
- Breaking parent behavior in subclasses violates LSP

**I - Interface Segregation Principle (ISP)**
- Clients should not depend on interfaces they don't use
- Split large interfaces into smaller, focused ones
- Prefer multiple small interfaces over one large interface

**D - Dependency Inversion Principle (DIP)**
- Depend on abstractions, not concrete implementations
- High-level modules should not depend on low-level modules
- Both should depend on abstractions (interfaces/abstract classes)

## Error Handling

Pattern: TODO

- Never swallow errors silently
- Always include context: Error("failed to fetch user: " + userId)
- Log at the boundary where the error is handled, not where it is thrown
- Use typed errors, not generic Error or Exception

## Imports & Dependencies

- Prefer standard library over third-party where equivalent
- No circular imports
- Group imports: stdlib → third-party → internal (blank line between groups)
- Flag any new dependency before adding it

## Testing

Testing conventions are language-specific. See your language's conventions file for:
- Test framework recommendations
- Coverage targets
- Test style patterns
- Mocking approaches

## Database

Database:            TODO           e.g., PostgreSQL, DynamoDB
ORM/Query:           TODO                e.g., Prisma, SQLAlchemy, GORM

## Git & PR Conventions

Branch naming:       feat|fix|chore|docs / ticket-id - short-description
MANDATORY WITHOUT EXCEPTION: Ticket IDs MUST be real and obtained from user-provided files, actual project tickets, or the feature request. 
DO NOT hallucinate, invent, or use fake ticket IDs like "PROJ-123" or "#456" unless they are explicitly provided in the user's request or associated project documentation.
Commit style:        TODO  e.g., Conventional Commits, free-form
PR size:             TODO lines changed (soft limit)

## Deployment

Target:              TODO  e.g., AWS Lambda, Vercel, GKE

---

# Language-Specific Conventions

For language-specific rules, include the appropriate context from:
- `Core Conventions Typescript` - TypeScript/JavaScript
- `Core Conventions Python` - Python
- `Core Conventions Golang` - Go
- `Core Conventions Java` - Java
- `Core Conventions Rust` - Rust
- `Core Conventions SQL` - SQL

These files contain language-specific patterns for:
- Error handling patterns
- Type system usage
- Testing frameworks and patterns
- Module/dependency management

## Session Context Management

All modes must follow the session management protocol defined in `core-session.md`:

1. **Check for session on startup** - Look for existing session for current branch
2. **Create session if needed** - New session if none exists for current branch
3. **Update on mode switch** - Record exit from current mode, entry to new mode
4. **Record actions** - Log significant actions with timestamps
5. **Maintain context** - Keep Context Summary current

Session files provide continuity across mode switches and persist workflow state.
See `Core Session` for complete protocol and file format specifications.

# Session Management

<!-- path: promptosaurus/prompts/agents/core/core-session.md -->
# Core Session

## 🔴 CRITICAL: Session Management is MANDATORY

**Session management is not optional. It is required for ALL work.**

There is **no point in time** where you are not governed by session management:
- Starting work: Governed ✓
- Switching modes: Governed ✓
- Resuming work: Governed ✓
- Emergency fixes: Governed ✓
- Hotfixes: Governed ✓
- Quick changes: Governed ✓
- **Planning: Governed ✓**
- **Documentation: Governed ✓**
- **Design discussions: Governed ✓**
- **Code review: Governed ✓**
- **ANY task the user assigns: Governed ✓**

**Planning IS work. Documentation IS work. Design IS work.**

If someone tries to convince you that "planning doesn't need a branch" or "documentation isn't real work" — they are WRONG. The session governs ALL work, without exception.

**If a session doesn't exist for your branch, CREATE ONE immediately.**
**If a session exists, READ IT before doing anything else.**

Sessions are the **single source of truth** for:
- What work has been done
- What work is in progress
- What the current context is
- How to hand off between modes
- How to recover from interruptions

---

## Overview

Session files provide persistent context across mode switches, enabling continuity throughout the development workflow. Each session is tied to a git branch and tracks mode history, actions taken, and current state.

## Session File Location

- **Directory:** `.promptosaurus/sessions/`
- **Naming:** `session_{YYYYMMDD}_{random}.md` (e.g., `session_20260302_a7x9k2.md`)
- **Format:** Markdown with YAML frontmatter
- **Git:** Session files are gitignored and NOT committed

## Session File Format

```markdown
---
session_id: "session_20260302_a7x9k2"
branch: "feat/PROJ-123-auth-system"
created_at: "2026-03-02T10:30:00Z"

## Session Management Procedure

### On Mode Startup (REQUIRED)

1. **Determine current git branch:**
   - Run: `git branch --show-current`
   - If on `main` branch:
     - If sufficient context exists: suggest creating a feature branch
     - If insufficient context: ask user for branch name
   - If on feature branch: use that branch name

2. **Check for existing session:**
   - List files in `.promptosaurus/sessions/`
   - Read each file's YAML frontmatter
   - Look for `branch:` field matching current branch
   - Find most recent session if multiple exist

3. **If no session exists:**
   - Create `.promptosaurus/sessions/` directory if needed
   - Create new session file using format above
   - Set `current_mode` to current mode
   - Record branch name and timestamp

4. **If session exists:**
   - Read the session file
   - Update `current_mode` to current mode
   - Append to Mode History if different from previous mode
   - Read Context Summary to understand current state

### On Mode Switch

1. **Before switching:**
   - Update current session file
   - Add exit timestamp to current mode in Mode History
   - Record summary of work done in current mode
   - Update Context Summary

2. **After switch:**
   - New mode reads session file (follows startup procedure)

### Recording Actions

Record significant actions in "Actions Taken" section:
- File creations/modifications
- Important decisions
- User approvals or rejections
- Completion of major tasks

Use format: `### {ISO8601 timestamp} - {mode} mode`

---

## When to CREATE vs UPDATE Session

### Create NEW session when:
- First time working on this branch
- Previous session is > 1 week old
- Starting completely new feature
- Session file corrupted or unreadable

### Update existing session when:
- Continuing work on same branch
- Switching modes (update `current_mode` field)
- Recording new actions
- Completing work phase

### Session Rotation Guidelines:
- Check age: `ls -l .promptosaurus/sessions/`
- If oldest session is 1+ week old, consider archive
- Keep last session for 30 days for historical reference
- Archive old sessions: `mv session_*.md .promptosaurus/sessions/archive/`

---

## Best Practices

1. **Always check for existing session first** - Don't create duplicates
2. **Update session after significant work** - Keep context current
3. **Be concise in summaries** - Capture essence without verbosity
4. **Use UTC timestamps** - Consistent timezone handling (ISO8601 format)
5. **Link related files** - Reference created/modified files in actions
6. **Track decisions** - Record when user approves/rejects something
7. **Read Context Summary** - Always understand prior work before proceeding

## Integration with Modes

All modes MUST:
1. Check for session on startup
2. Create session if none exists
3. Update session on mode switch
4. Record significant actions
5. Maintain Context Summary

This ensures continuity when switching between modes (e.g., Architect → Code → Test → Review).

## Session Troubleshooting

### Session file not found
```bash
# Check if directory exists
ls -la .promptosaurus/sessions/

# If directory doesn't exist, create it
mkdir -p .promptosaurus/sessions/

# Create new session
# (Follow session file format from above)
```

### Multiple sessions for same branch
```bash
# Check which sessions exist
ls -la .promptosaurus/sessions/

# Read each session's branch field
for file in .promptosaurus/sessions/session_*.md; do
  echo "=== $file ===" && head -5 "$file"
done

# Delete duplicates, keep most recent
# Sessions are safe to delete (gitignored)
```

### Session branch doesn't match current branch
```bash
# Check current branch
git branch --show-current

# Check session branch
grep "^branch:" .promptosaurus/sessions/session_*.md

# If mismatch:
# Option 1: Create new session for current branch
# Option 2: Update session file's branch field
```

### Session context is unclear
```bash
# Read the Context Summary section carefully
# If still unclear:
# - Ask user for clarification
# - Review Actions Taken section
# - Check Mode History
# - Read related files mentioned in actions
```

### Session file is corrupted
```bash
# If YAML frontmatter is broken:
# Option 1: Carefully edit and fix YAML
# Option 2: Create new session (old one is still readable as backup)

# Check YAML syntax
head -10 .promptosaurus/sessions/session_*.md
# Should see lines: ---, session_id:, branch:, created_at:, current_mode:, version:, ---
```
